/* This file is for inclusion into client (your!) code.

   You can use these macros to manipulate and query Valgrind's 
   execution inside your own programs.

   The resulting executables will still run without Valgrind, just a
   little bit more slowly than they otherwise would, but otherwise
   unchanged.  When not running on valgrind, each client request
   consumes very few (eg. 7) instructions, so the resulting performance
   loss is negligible unless you plan to execute client requests
   millions of times per second.  Nevertheless, if that is still a
   problem, you can compile with the NVALGRIND symbol defined (gcc
   -DNVALGRIND) so that client requests are not even compiled in.  */

/* The following defines the magic code sequences which the JITter
   spots and handles magically.  Don't look too closely at them as
   they will rot your brain.

   The assembly code sequences for all architectures is in this one
   file.  This is because this file must be stand-alone, and we don't
   want to have multiple files.

   For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
   value gets put in the return slot, so that everything works when
   this is executed not under Valgrind.  Args are passed in a memory
   block, and so there's no intrinsic limit to the number that could
   be passed, but it's currently five.
   
   The macro args are: 
      _zzq_rlval    result lvalue
      _zzq_default  default value (result returned when running on real CPU)
      _zzq_request  request code
      _zzq_arg1..5  request params

   The other two macros are used to support function wrapping, and are
   a lot simpler.  VALGRIND_GET_NR_CONTEXT returns the value of the
   guest's NRADDR pseudo-register and whatever other information is
   needed to safely run the call original from the wrapper: on
   ppc64-linux, the R2 value at the divert point is also needed.  This
   information is abstracted into a user-visible type, OrigFn.

   VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
   guest, but guarantees that the branch instruction will not be
   redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
   branch-and-link-to-r11.  VALGRIND_CALL_NOREDIR is just text, not a
   complete inline asm, since it needs to be combined with more magic
   inline asm stuff to be useful.

/* This section defines magic (a.k.a appalling-hack) macros for doing
   guaranteed-no-redirection macros, so as to get from function
   wrappers to the functions they are wrapping.  The whole point is to
   construct standard call sequences, but to do the call itself with a
   special no-redirect call pseudo-instruction that the JIT
   understands and handles specially.  This section is long and
   repetitious, and I can't see a way to make it shorter.

   The naming scheme is as follows:

      CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc}

   'W' stands for "word" and 'v' for "void".  Hence there are
   different macros for calling arity 0, 1, 2, 3, 4, etc, functions,
   and for each, the possibility of returning a word-typed result, or
   no result.

   VG_WRAP_FUNCTION_Z{U,Z} in pub_tool_redir.h.  NOTE also: inserts
   the default behaviour equivalance class tag "0000" into the name.
   See pub_tool_redir.h for details -- normally you don't need to

   the CFA is in %rsp, then unwinding may fail, because what's at the
   CFA is not what gcc "expected" when it constructs the CFIs for the
   places where the macros are instantiated.

   But we can't just add a CFI annotation to increase the CFA offset
   by 128, to match the sub of 128 from %rsp, because we don't know
   whether gcc has chosen %rsp as the CFA at that point, or whether it
   has chosen some other register (eg, %rbp).  In the latter case,
   adding a CFI annotation to change the CFA offset is simply wrong.

   So the solution is to get hold of the CFA using
   __builtin_dwarf_cfa(), put it in a known register, and add a
   CFI annotation to say what the register is.  We choose %rbp for
   this (perhaps perversely), because:

   (1) %rbp is already subject to unwinding.  If a new register was
       chosen then the unwinder would have to unwind it in all stack
       traces, which is expensive, and

   (2) %rbp is already subject to precise exception updates in the
       JIT.  If a new register was chosen, we'd have to have precise
       exceptions for it too, which reduces performance of the
       generated code.

   However .. one extra complication.  We can't just whack the result
   of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
   list of trashed registers at the end of the inline assembly
   fragments; gcc won't allow %rbp to appear in that list.  Hence
   instead we need to stash %rbp in %r15 for the duration of the asm,
   and say that %r15 is trashed instead.  gcc seems happy to go with
   that.

   Oh .. and this all needs to be conditionalised so that it is
   unchanged from before this commit, when compiled with older gccs
   that don't support __builtin_dwarf_cfa.  Furthermore, since
   this header file is freestanding, it has to be independent of
   config.h, and so the following conditionalisation cannot depend on
   configure time checks.

   Although it's not clear from
   'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
   this expression excludes Darwin.
   .cfi directives in Darwin assembly appear to be completely
   different and I haven't investigated how they work.

   For even more entertainment value, note we have to use the
   completely undocumented __builtin_dwarf_cfa(), which appears to
   really compute the CFA, whereas __builtin_frame_address(0) claims
   to but actually doesn't.  See
   https://bugs.kde.org/show_bug.cgi?id=243270#c47

/* These CALL_FN_ macros assume that on amd64-linux, sizeof(unsigned

/* NB 9 Sept 07.  There is a nasty kludge here in all these CALL_FN_
   macros.  In order not to trash the stack redzone, we need to drop
   %rsp by 128 before the hidden call, and restore afterwards.  The
   nastyness is that it is only by luck that the stack still appears
   to be unwindable during the hidden call - since then the behaviour
   of any routine using this macro does not match what the CFI data
   says.  Sigh.

   Why is this important?  Imagine that a wrapper has a stack
   allocated local, and passes to the hidden call, a pointer to it.
   Because gcc does not know about the hidden call, it may allocate
   that local in the redzone.  Unfortunately the hidden call may then
   trash it before it comes to use it.  So we must step clear of the
   redzone, for the duration of the hidden call, to make it safe.

   Probably the same problem afflicts the other redzone-style ABIs too
   (ppc64-linux); but for those, the stack is
   self describing (none of this CFI nonsense) so at least messing
   with the stack pointer doesn't give a danger of non-unwindable
   stack. */

/* These requests allow control to move from the simulated CPU to the

   Note that the current ThreadId is inserted as the first argument.
   So this call:

     VALGRIND_NON_SIMD_CALL2(f, arg1, arg2)

   requires f to have this signature:

     Word f(Word tid, Word arg1, Word arg2)

   where "Word" is a word-sized type.

   Note that these client requests are not entirely reliable.  For example,
   if you call a function with them that subsequently calls printf(),
   there's a high chance Valgrind will crash.  Generally, your prospects of
   these working are made higher if the called function does not refer to
   any global variables, and does not refer to any libc or other functions
   (printf et al).  Any kind of entanglement with libc or dynamic linking is
   likely to have a bad outcome, for tricky reasons which we've grappled
   with a lot in the past.

/* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
   when heap blocks are allocated in order to give accurate results.  This
   happens automatically for the standard allocator functions such as
   malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
   delete[], etc.

   But if your program uses a custom allocator, this doesn't automatically
   happen, and Valgrind will not do as well.  For example, if you allocate
   superblocks with mmap() and then allocates chunks of the superblocks, all
   Valgrind's observations will be at the mmap() level and it won't know that
   the chunks should be considered separate entities.  In Memcheck's case,
   that means you probably won't get heap block overrun detection (because
   there won't be redzones marked as unaddressable) and you definitely won't
   get any leak detection.

   The following client requests allow a custom allocator to be annotated so
   that it can be handled accurately by Valgrind.

   VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
   by a malloc()-like function.  For Memcheck (an illustrative case), this
   does two things:

   - It records that the block has been allocated.  This means any addresses
     within the block mentioned in error messages will be
     identified as belonging to the block.  It also means that if the block
     isn't freed it will be detected by the leak checker.

   - It marks the block as being addressable and undefined (if 'is_zeroed' is
     not set), or addressable and defined (if 'is_zeroed' is set).  This
     controls how accesses to the block by the program are handled.
   
   'addr' is the start of the usable block (ie. after any
   redzone), 'sizeB' is its size.  'rzB' is the redzone size if the allocator
   can apply redzones -- these are blocks of padding at the start and end of
   each block.  Adding redzones is recommended as it makes it much more likely
   Valgrind will spot block overruns.  `is_zeroed' indicates if the memory is
   zeroed (or filled with another predictable value), as is the case for
   calloc().
   
   VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
   heap block -- that will be used by the client program -- is allocated.
   It's best to put it at the outermost level of the allocator if possible;
   for example, if you have a function my_alloc() which calls
   internal_alloc(), and the client request is put inside internal_alloc(),
   stack traces relating to the heap block will contain entries for both
   my_alloc() and internal_alloc(), which is probably not what you want.

   For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
   custom blocks from within a heap block, B, that has been allocated with
   malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
   -- the custom blocks will take precedence.

   VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK.  For
   Memcheck, it does two things:

   - It records that the block has been deallocated.  This assumes that the
     block was annotated as having been allocated via
     VALGRIND_MALLOCLIKE_BLOCK.  Otherwise, an error will be issued.

   - It marks the block as being unaddressable.

   VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
   heap block is deallocated.

   VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
   Memcheck, it does four things:

   - It records that the size of a block has been changed.  This assumes that
     the block was annotated as having been allocated via
     VALGRIND_MALLOCLIKE_BLOCK.  Otherwise, an error will be issued.

   - If the block shrunk, it marks the freed memory as being unaddressable.

   - If the block grew, it marks the new area as undefined and defines a red
     zone past the end of the new block.

   - The V-bits of the overlap between the old and the new block are preserved.

   VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
   and before deallocation of the old block.

   In many cases, these three client requests will not be enough to get your
   allocator working well with Memcheck.  More specifically, if your allocator
   writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
   will be necessary to mark the memory as addressable just before the zeroing
   occurs, otherwise you'll get a lot of invalid write errors.  For example,
   you'll need to do this if your allocator recycles freed blocks, but it
   zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
   Alternatively, if your allocator reuses freed blocks for allocator-internal
   data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.

   Really, what's happening is a blurring of the lines between the client
   program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
   memory should be considered unaddressable to the client program, but the
   allocator knows more than the rest of the client program and so may be able
   to safely access it.  Extra client requests are necessary for Valgrind to
   understand the distinction between the allocator and the rest of the
   program.
